The trachea and bronchi form the tracheobronchial tree. The trachea is situated between the lower end of the larynx and the center of the chest, where it splits into the two bronchi at a ridge called the carina.arly diagnosis is important to prevent complications, which include stenosis (narrowing) of the airway, respiratory tract infection, and damage to the lung tissue. Diagnosis involves procedures such as bronchoscopy, radiography, and x-ray computed tomography to visualize the tracheobronchial tree.
Avogadro's number is the number of atoms required to make 1 gram of molecular hydrogen (not including the heavier isotopes of hydrogen). Sodium has a standard atomic weight of 22.99 amu (atomic mass units). A mole of Sodium atoms would weigh 22.99 grams.
